From: "THE 131ST U.S. INFANTRY (FIRST INFANTRY ILLINOIS NATIONAL GUARD) IN THE WORLD WAR; NARRATIVE—OPERATIONS—STATISTICS" By COLONEL JOSEPH B. SANBORN p. 330: Guley, 2062921, Pvt. William, Co. M. Information given by Richard H. Buvens, Jr., 2nd Lt. Eye witnesses of the death of Private William Guley cannot be found. Current opinion is as follows: He was killed instantly by a shell during the advance ou the Bois de Warville, on Nov. 10, 1918.p. 189: "On November 10th, 1918, during the attack on the Bois de Harville, the left of the line, was delayed considerably, because of the loss of its officers and a large number of N. C. O's. The enemy machine gun fire was very heavy, which greatly endangered our left flank. Second Lieutenant Buvens noticed the danger from the right, and he immediately picked up two squads and rushed to the left, and flanked two machine gun nests, capturing the guns and killing the two crews. By this act of bravery the line was consolidated, the advance was made possible, and the objective was later gained."
